Why Portuguese ?
Learning Portuguese does take a lot of work, I admit it is a challenge (especially grammar and pronunciation), but there are a lot of benefits to being able to speak Portuguese as well. It will empower you and can also be fun and rewarding. Learning the language is the best way to understand a culture.
You can live in Portugal (particularly in the Algarve and Lisbon) and never learn to say anything other than "bom dia" or "obrigado", but you will always going to live in an english-speaking bubble.
Speaking Portuguese is an asset in today's globalised world. With about 300 million speakers, Portuguese is the 5th most spoken language in the world, the 3rd most spoken in the Western hemisphere (after English and Spanish) and the most spoken in the Southern hemisphere.
People who do not know European Portuguese often think the Portuguese way of speaking looks like the Russian language and this can be explained with the richness of phonetics. While speakers from other latin languages (Spanish, Italian, French) show in general some difficulties to speak other languages, portuguese people seem to speak other idioms with ease, because portuguese language has a richness of sounds that those languages don't have.
European Portuguese is a beautiful language that deserves to be made easily accessible to learners worldwide
